Abstract (en)
A tripod type constant velocity universal joint has an outer member (1) having three axially extending track grooves (2) formed in an inner circumferential surface thereof, each of the track grooves having roller guide surfaces on a pair of opposing side walls thereof. A tripod member (4) has three radially projecting trunnions (5). Rollers (7) are rotatably carried on the trunnions (5), respectively, through a series of cylindrical rolling elements (6), the rollers (7) being accommodated in the track grooves (2) respectively, so that the rollers (7) are movably axially of the outer member (1) with each said roller (7) rolling along one of the opposing roller guide surfaces. Each said roller (7) with an annular projection at an end thereof and a sereis of said rolling elements (6) retained along an inner periphery of said roller (7) form an assembly capable of preventing said rolling elements (6) from dispersing even before said assembly is mounted on a respective trunnion (5). <IMAGE>
